Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing processing technology, specifically a bearing outer ring grinding device. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearings generally consist of an inner and outer ring. During the manufacturing process, the outer ring of the bearing inevitably has some burrs. These burrs can have adverse effects during later use and installation. Therefore, workers usually use steel brushes to grind down these burrs.
[0003] A search revealed that patent CN220680242U discloses a bearing outer ring grinding device, relating to the field of bearing manufacturing technology. The device includes a base plate with two support plates connected to its upper side. Two support plates are connected to a sliding rod between them. Two support plates are also connected to a lead screw between them. A motor is connected to one side of the lead screw. A moving block is sleeved on the outer wall of the lead screw, and the moving block is fitted onto the outer wall of the sliding rod. A vertical plate is connected to the upper side of the moving block, and a motor is connected to one side of the vertical plate. A turntable is connected to one side of the motor. In this invention, a V-shaped inner support plate is inserted into the inner wall of the bearing cylinder. The inner wall of the bearing cylinder compresses the V-shaped inner support plate, a spring, and a spring. When the V-shaped inner support plate is fully inserted into the inner wall of the bearing cylinder, the spring and spring press the V-shaped inner support plate against the inner wall of the bearing cylinder, thus fixing the bearing cylinder to the outer wall of the fixing block. This design can accommodate bearing cylinders of various outer diameters.
[0004] While existing technologies can accommodate grinding bearing housings of various outer diameters, they are limited to grinding individual bearing outer rings. This necessitates frequent loading and unloading by personnel, resulting in low efficiency and slow grinding speed. Therefore, we provide a bearing outer ring grinding device to address these issues. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a bearing outer ring grinding device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing outer ring grinding device, comprising a worktable, an L-shaped bracket and two upright plates fixedly connected to the worktable, a swing column rotatably disposed between the two upright plates, a rotating column rotatably connected to the middle of the swing column, a second motor installed at the bottom center of the swing column, a sliding groove formed in the middle of the rotating column, a bidirectional lead screw rotatably connected to the inner top wall of the sliding groove, and the output end of the second motor passing through the swing column and extending into the sliding groove to connect with the bottom end of the bidirectional lead screw, a pressing mechanism for fixing the bearing being provided on the surface of the bidirectional lead screw, and a transmission mechanism for driving the rotating column to rotate and a grinding assembly for grinding the bearing outer ring being provided on the L-shaped bracket.
[0007] Preferably, a first motor is mounted on the side of one of the upright plates, and the output end of the first motor is connected to one end of the swing column.
[0008] Preferably, a limiting block is fixedly connected to the side of another of the upright plates, and a positioning block is fixedly connected to the end of the swing column away from the first motor, and the positioning block is in contact with the limiting block.
[0009] Preferably, the transmission mechanism includes a third motor, which is mounted on the top of the L-shaped bracket. The output end of the third motor is fixedly connected to a second gear, and the top of the rotating column is fixedly connected to a first gear, which meshes with the second gear.
[0010] Preferably, a guide seat is fixedly connected to the top of the rotating column, and the guide seat is located below the first gear.
[0011] Preferably, the extrusion mechanism includes two sleeve plates and two extrusion plates, and the two extrusion plates are adapted to the inner wall of the outer ring of the bearing. The two sleeve plates are slidably disposed in the sliding groove and sleeved on the surface of the rotating column. The opposing threads of the two sleeve plates are threaded onto the surface of the bidirectional lead screw. The two extrusion plates are located on both sides of the rotating column. Two connecting rods are hinged to the adjacent surfaces of the two extrusion plates, and one end of each connecting rod is hinged to the two sleeve plates. The top ends of the two extrusion plates are located below the guide seat.
[0012] Preferably, the grinding assembly includes a positioning block, which is installed in the middle of the L-shaped bracket. The telescopic end of the positioning block is fixedly connected to a grinding plate, and the grinding plate is adapted to the outer ring of the bearing.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the coordinated arrangement of a workbench, a first motor, an L-shaped bracket, a vertical plate, a swing column, a rotating column, a second motor, a sliding groove, a bidirectional lead screw, a pressing mechanism, a transmission mechanism, and a grinding mechanism, enables the first motor to control the rotating column to tilt and swing forward, causing the first gear to move away from the second gear. Then, multiple bearing outer rings are sequentially placed onto the rotating column. Next, the first motor controls the rotating column to swing until it is vertical, causing the first gear to automatically mesh with the second gear. Subsequently, the second motor drives the bidirectional lead screw to rotate, causing the two pressing plates to move outward and press and fix the inner wall of each bearing outer ring. Finally, a third motor drives the second gear to rotate, thereby causing the rotating column to... The system rotates each bearing outer ring, then controls the operation of the electric push rod to push the grinding plate into contact with the surface of each bearing outer ring, thus initiating the grinding process. Once the bearing outer rings on the rotating column have been ground, the electric push rod controls the grinding plate to reset and stops the operation of the third motor. At this point, the operation of the first motor controls the rotating column to swing forward, and the operation of the second motor causes the two pressing plates to release their fixation on the bearing outer rings. Subsequently, personnel can directly remove multiple bearing outer rings from the rotating column. Then, the unground bearing outer rings are put back onto the rotating column for subsequent grinding, thereby improving the grinding efficiency of bearing outer rings and eliminating the need for frequent grinding of individual bearing outer rings.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1, as Figure 1-5 As shown, this embodiment proposes a bearing outer ring grinding device, including a worktable 1. An L-shaped bracket 12 and two upright plates 2 are fixedly connected to the worktable 1. The L-shaped bracket 12 is located at the rear of the worktable 1, and the two upright plates 2 are located on both sides of the worktable 1. A swing column 6 is rotatably arranged between the two upright plates 2. A rotating column 20 is rotatably connected to the middle of the swing column 6, allowing the rotating column 20 to rotate in the middle of the swing column 6. A second motor 15 is installed at the bottom center of the swing column 6. The output end of the second motor 15 does not have a self-locking function, so external force can rotate the output end of the second motor 15. A sliding groove 19 is opened in the middle of the rotating column 20. A bidirectional lead screw 18 is rotatably connected to the inner top wall of the sliding groove 19. The output end of the second motor 15 passes through the swing column 6 and extends into the sliding groove 19 to connect with the bottom end of the bidirectional lead screw 18. The rotation of the second motor 15 can drive the bidirectional lead screw 18 to rotate. The surface of the bidirectional lead screw 18 is equipped with a pressing mechanism for fixing the bearing. This pressing mechanism can press and fix the bearing outer ring sleeved on the outside of the rotating column 20, thus ensuring the stability of subsequent grinding. The L-shaped bracket 12 is equipped with a transmission mechanism for driving the rotating column 20 to rotate and a grinding assembly for grinding the bearing outer ring. With the transmission mechanism, once the bearing outer ring is fixed on the surface of the rotating column 20, the rotating column 20 can be rotated, thereby rotating each bearing outer ring. Combined with the grinding assembly, multiple bearing outer ring surfaces can be ground simultaneously, improving the efficiency of bearing outer ring grinding and eliminating the need for frequent grinding of individual bearing outer rings. The machinery, parts, and equipment in this device all use conventional models from the existing technology, and the circuit connections also use conventional connection methods from the existing technology, which will not be detailed here.
[0018] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details: like Figure 1 and Figure 2As shown, a first motor 5 is installed on the side of one of the upright plates 2, and the output end of the first motor 5 is connected to one end of the swing column 6. The first motor 5 is a worm gear motor, so the output end of the first motor 5 has a self-locking function. When the output end of the first motor 5 stops rotating, it will not rotate by external force, thus ensuring the stability of the swing column 6. The rotation of the swing column 6 between the two upright plates 2 can be controlled by the operation of the first motor 5, thereby controlling the rotating column 20 to tilt and swing to one side. This is beneficial for personnel to put multiple bearing outer rings on the rotating column 20, and also facilitates subsequent unloading.
[0019] like Figure 1 , Figure 2 and Figure 4 As shown, a limiting block 4 is fixedly connected to the side of another upright plate 2, and a positioning block 3 is fixedly connected to the end of the swing column 6 away from the first motor 5. The positioning block 3 is in contact with the limiting block 4. With the above structure, when the rotating column 20 swings to a vertical position, the side of the positioning block 3 will contact the side of the limiting block 4, thus ensuring the vertical stability of the rotating column 20.
[0020] like Figures 1 to 4 As shown, the transmission mechanism includes a third motor 11, which is mounted on the top of the L-shaped bracket 12. A second gear 10 is fixedly connected to the output end of the third motor 11, and a first gear 7 is fixedly connected to the top of the rotating column 20. The first gear 7 meshes with the second gear 10. The third motor 11 is a worm gear motor, therefore its output end has a self-locking property, preventing the second gear 10 from rotating arbitrarily. With this structure, when multiple bearing outer rings are fitted over the two extrusion plates 9, the first motor 5 can drive the swing column 6 to swing, making the rotating column 20 vertical. This allows the first gear 7 to automatically mesh with the third motor 11 upon contact. To prevent the rotating column 20 from rotating arbitrarily, the second motor 15 is used to support and fix the inner wall of the outer ring of each bearing through the extrusion mechanism. Finally, the third motor 11 drives the second gear 10 to rotate, which in turn drives the first gear 7 to rotate the rotating column 20. The rotating column 20 will then rotate in the middle of the swing column 6. Furthermore, the two sleeve plates 17 and the two extrusion plates 9 rotate synchronously, thereby driving the outer ring of each bearing to rotate. Since the output end of the second motor 15 does not have a self-locking effect, when the rotating column 20 rotates, it will drive the bidirectional lead screw 18 to rotate through the two sleeve plates 17, so that the bottom end of the bidirectional lead screw 18 drives the output end of the second motor 15 to rotate normally.
[0021] like Figures 1 to 4 As shown, a guide seat 8 is fixedly connected to the top of the rotating column 20, and the guide seat 8 is located below the first gear 7. With the above structure, the outer ring of the bearing can be easily fitted outside the rotating column 20 and outside the two extrusion plates 9.
[0022] like Figures 1 to 3 and Figure 5 As shown, the extrusion mechanism includes two sleeve plates 17 and two extrusion plates 9. The two extrusion plates 9 are adapted to the inner wall of the outer ring of the bearing. Both sleeve plates 17 are slidably disposed in the sliding groove 19 and sleeved on the surface of the rotating column 20. The two sleeve plates 17 are threaded onto the surface of the bidirectional lead screw 18. The two extrusion plates 9 are located on both sides of the rotating column 20. Two connecting rods 16 are hinged to the adjacent surfaces of the two extrusion plates 9, and one end of each connecting rod 16 is hinged to one of the two sleeve plates 17. The top ends of the two extrusion plates 9 are located below the guide seat 8. With the above structure, the second electric... When the machine 15 rotates the bidirectional lead screw 18, the two sleeve plates 17 can move relative to each other on the surface of the rotating column 20, thereby allowing the two extrusion plates 9 to extend outward or inward, and thus extruding and fixing the bearing outer ring sleeved on the outside of the rotating column 20, preventing the bearing outer ring from swinging randomly. In addition, the outer layer of the extrusion plate 9 is made of silicone, so it will not damage the bearing outer ring when extruding and fixing it. It can extrude and fix bearing outer rings of different sizes. When the outer layer of the extrusion plate 9 extrudes the inner wall of the bearing outer ring, it will deform, thus it can adapt to bearing outer rings of different diameters.
[0023] like Figures 1 to 4 As shown, the grinding assembly includes a positioning block 3, which is installed in the middle of the L-shaped bracket 12. The telescopic end of the positioning block 3 is fixedly connected to a grinding plate 14, which is adapted to the bearing outer ring. With the above structure, when multiple bearing outer rings are fitted outside the rotating column 20 and fixed by two pressing plates 9, the positioning block 3 drives the grinding plate 14 to move towards and adhere to the bearing outer ring. Finally, the transmission mechanism drives the rotating column 20 to rotate each bearing outer ring, thereby grinding it at the grinding plate 14. After the bearing outer ring is ground, the positioning block 3 is controlled to drive the grinding plate 14 to retract, so that the rotating column 20 can be tilted and the bearing outer ring can be removed normally. In order to make the grinding plate 14 easy to replace, the grinding plate 14 can be fixed to the telescopic end of the positioning block 3 by a bolt assembly. Therefore, it can be replaced according to the bearing outer ring of different sizes, which improves the practicality of the device.
[0024] The working principle and usage process of this utility model are as follows: When grinding the outer ring of a bearing, firstly, the operation of the first motor 5 controls the rotating column 20 to tilt and swing forward, so that the first gear 7 moves away from the second gear 10. Then, multiple bearing outer rings are sequentially placed on the surface of the rotating column 20 and positioned outside the two pressing plates 9. Next, the first motor 5 controls the rotating column 20 to swing until it is vertical, so that the first gear 7 automatically meshes with the second gear 10, thereby preventing the rotating column 20 from rotating arbitrarily. Then, the operation of the second motor 15 drives the bidirectional lead screw 18 to rotate, which controls the two pressing plates 9 to move outward, thus pressing and fixing the inner wall of each bearing outer ring. Finally, the third motor 11 drives the second gear 10 to rotate, thereby causing the rotating column 20 to... The motor drives each bearing outer ring to rotate, and then controls the operation of the electric push rod 13 to push the grinding plate 14 to contact the surface of each bearing outer ring, thus starting the grinding process. After the bearing outer ring on the rotating column 20 has been ground, the electric push rod 13 controls the grinding plate 14 to reset and stops the operation of the third motor 11. At this time, the operation of the first motor 5 controls the rotating column 20 to swing forward, and the operation of the second motor 15 causes the two pressing plates 9 to release the fixing of the bearing outer ring. Then, the personnel can directly remove multiple bearing outer rings from the rotating column 20, and then put the multiple unground bearing outer rings back onto the rotating column 20 for subsequent grinding, thereby improving the grinding efficiency of bearing outer rings and eliminating the need for personnel to frequently grind individual bearing outer rings.
